The gripping de- .Vices are duplicates of each other, and a de script-ion oi' one will .suiiice `for all. there being four carried bv euch dish. Each movable gripper '39 is carried by the. outer end of an orn'i of o roclisshnft Gai having o suitohle bearing at and provided with a toothed segment 6G (Figs. il. and 6). y'l`he rock-shaft has o projection 67 adopted to be acted upon o springpressed plunger GS to hold the roch-shaft with the. grippers (i2 in their open or closed position. Mounted toreciprocote in o portion of the brochet arm 19 is o bor G9 having a rack or toothed portion engaging the toothed segment of 'the rock-shaft, the other end oi' said bor being beveled at 70. The operation oi .these portions of the machine will be more readily` understood presently.

Each arm 'Z4 or the movable knife e cam plate 8GV adapted, when the lrniie scende' to the position shown in Figs. l, and 6, to engage o. curved or cam surface of the-arm which :berries the gripper 62, soas to press seid gripper to the zposition shown in Fig. G, snapping the com proiection 67 past the spring piunger so that the said spring plunger will cause the gripper-arm to yieldinglj7 grasp the paper :c between it sind thestetionziry gripping .mehr ber or stud 63.*- Lugs 8l secured lo the xed bracket arms "i2 are provided with stops 82 which .cooperate with stops 83 carried by the knife arms 74 to limit the flowermost position of the movable knife.

Above that portion of the mechanism 0ccpicd by the carriers when in position Z) i chute or Well along' which may "loe in the application filed January ii, wir. solo No. 602,062, by H. A. Sevigne. rEhe rear Nall 84 of this chute or well is preferably sprinff mounted, and the lower section of the iront Woll is shown l hinged a Si?, and having an arm 87 which engages e pin 88 to limit the inward fposition to which said .section S5 can lhe pressed hy :i spring plunger wing 90 pivotell at 9i to :i1-ms 9&2 (only one arm being shown) l@ pivoted at 93 and the` lower position of which is limited by e stop pin 9i, is pressed toward the puth of movement of the lont by spring,l 95 mounted in a recess iii the arm and acting upon :i pin projecting M5 rearwardly from Suid Wino- 90. l'llliis yieldingly mounted "ving 90 is lor the purpose of bridging the space between the lower edge of the rear Well 84 and the loaf carrier7 so a. to insure the Wrapper section im being held in smooth condition While the loef :ind

the Wrapper section n" are being pushed upwardly, as hereinzitter described.' But smid wing .90 muet be shitted out of position when the Emilie rises so that the paper con m5 be drawn directly upwardly when o loaf is being; trunsierred 'from position o to oosition Z). '.lliis is because the ki'iie must De independently lifted by its com high enough so that it will not hear upon. the peper as it l1S@ position o is again reached. The de- 90 arranged or mounted end folders of the type M36 is being; drawn as just described. i'oi this reason, thewing is carried by the arms 92, which arins 92 are engaged by the arras 7l of the movable knife wlienthe latter swings upwardly to the dotted line position sli/own in Fig. l, so as to litt said arms 92 and the wing 90 to the dotted line position indicated. Afterward, the liniiie descende, it deiiects the paper downwardly, drawing from the gravity roll 60, because the grippers 62 are still holding" the far end of the paper at the left hand side ci the loa occupying position b until the knife has descended to position to cut and at the time act upon the two raclr bars to open the movable grippers so that the Wrapper scc* tion ze is now entirely tree, but draped over the loaf as shown.

To next lil't the loaf in position b, and associated Wrapper ac into and through. chute and past the end. 'folders thereof, employ litters 96 which passv upwar il, through the spaces provided between tlv` two members 20 ot each carrier. lt ro the purpose of enabling the litters 96 v:o pass to elevate the loaves successively, that the spaces are provided, as best shown in Fig. l, lietween the duplicate members car ried by the two intermittently rotated, disks. Each lifter 96 is carried by an arm. 9i mounted on a rod 98 carried by chains 99, each rod having an arm l0() provided with a. roll lOl, said chaine being suitably supported by brackets 102 (Fig. 2), said brackets having path guides 1023, 104C for the ends of therod 98 andthe rolls 101 respectively. The details of this mechanism for guiding' the litters 96 in the proper path are not illustrated herein as the saine iorin no part of this invention, and may be the same or substantially the saine as illustrated andilescribed in the Sievignc application referred to.

The operation of the several parts having been described in connection with the con` struction thereof, description ot the operation of the machine a Whole will not he necessary.

is has been stated, the present invention relates particularly to means 'for associating` Wrappers with articles such as loaves oi? bread, the invention not including any specific means for completingr the Wrappino'. ln Fig. l of the drawings, however, l have illustrated at 105 and 106 means *for performing further wrapping; operations, said. meansl being similar to the helical corner 'folders illustrated and claimed in 'the `@enligne application referrclil to. lt is to be understood, however, that l may use any` other inechanisin'f'tor completing the iviap ping; operation. l

1With such means for completing the Wrapping, the machine comprises 'an intermittently rotatable carrier as described,

i, i icgoeo means lor severing a wrapper from a web or strip and placing it partially around the article in the carrier while the latter-mores :l rom position. a to position b, independent means such as the folders lll', 112 in' thc chute or Well for performing further Wrap,- ping operations, and a transferrer comprising the litters 96 'for reinoi'ing the article and its associated wrapper m from the carrier to the said chute or vWell alongside ot which are located the independent ywrapping Ey comparing; lFigs. l, EZ and e, it willbe seen that each, pair oit carrier members 20,- QO constitute a pocket capable oi receivingY a loa'li, and permitting the top ot 'the loafli to proiect from the pocket any distance according to the'height of the loaf. Fui therinore, each such pocket has an opening clear' through it, including its bottoni, to permit the passage of a lil-ter Slf which Jionstitutes t ansich-er. The members 2l), 9,0 provide the two ends of the pocket and what there is of its bottom and one side wall., while two movable arms' Ll? provide the other Wall. ll/hen a pocket moves troniv position o; (Fig. l) to ,position 7), the wrapper material is draped over the outside oit this aoclret as Well as the leali contained therein, and therefore there is no such pres sure upon the loai tending to crash it, would loe the case if the Wrapper material were 'pushed into the pocket usingn the-laat as the pusher. As the pocket starts from position a, the first strain oit' overcoming,l the inertia the supply roll or gravity roll 60, is borne by the gripper-s 62, (i3 which, then nioil'ing in a curved path, causes a gradual increase in the speed oi' pull ot the paper. a portion of the strain ot which is horno by the members 4:7 oiI 'the pocket. In hrieii. the wrapper is drapodnot only over the loaf, but also over'tlie pocket, thereby re d'ucing liability of a sol't loa't' being crushed by tie pressure resulting' from paper ton sion. 'lo enalile such dri lino; to be effected, there are.. as shown in l'ie'. l. spaces or ref f, between the several pockets of the series o l such area as to permit the complete draping described, the grippcrs being in such spaces or recesses, and thc cutter also moving into them successively. 'lhc amount oi Wrapper material drawn from the supply roll will, ot course, depend upon the extent to which the top of the loaf projectsfroin the pocket. Therefore, since the grippers have a lixecl location, relatively to the pool?.n ets and the cutter operates always in the saine location., the length of each section of wrapper material will be controlled hy the. height oli the particular loatl to be Wrapped in that scction. As already explained, this mnt-roi. olf site is etl'ected with no euch pres sure upon the loaf as to crush it.
